It’s nice when a simple test will solve your problem. SureTrack community member Bobomx250 had a Hyundai Sonata in their shop that was hard to start and would die after refueling. Codes led to a purge valve problem but functional and electrical tests did not indicate a bad component. They posed the question to the community, and with the help of fellow community member ericsautomotive and others, they were able to resolve the issue.
The following Real Fix summarizes the interaction between them in the community that led to the solution.
Vehicle
2004 Hyundai Sonata 2.7L
Title
Hard to start and dies after refueling, replaced EVAp purge valve.
Complaint
Customer complains that vehicle is hard to start and dies after refueling. Codes P0455, P1166 and P1167.
Diagnostic Steps Performed/Parts Replaced
Checked purge valve duty and resistance and checks out as good. What would cause the vehicle to be hard to start and stall after refueling.
Best Answer from Community Member ericsautomotive
Sounds like the EVAP purge valve is stuck open a little bit. Pull the purge valve off and see if you can blow through it. If you can, replace it.
Cause
Pulled the purge valve and could blow through it.
Correction
Replaced the EVAP purge valve and that fixed the problem.
